A dim screen on Xiaomi Redmi can ruin the experience of even the most powerful smartphone, especially in bright sunlight, when it becomes almost impossible to see notifications or text. But the problem is not always hardware limitations β often users simply do not know about all the options for adjusting the brightness in the environment. MIUI.
In this article, we'll look at all the ways you can brighten your screen on Redmi, from basic settings to little-known features that the manufacturer doesn't advertise. You'll learn how to get around the limitations of the system, why automatic adjustment sometimes works worse than manual, and what to do if even at maximum the screen seems dim. And also how to increase the brightness without sacrificing autonomy, because many people fear that a bright display will quickly discharge the battery.
Spoiler: on some Redmi models (e.g. Note 12 Pro)+ or K60) There's a hidden mode called Ultra Brightness, which only activates under certain conditions.
But first, let's get to the basics.
1. Standard brightness setting in MIUI
The most obvious way is to use a brightness slider in the notification curtain or the settings menu, but even here, there are nuances that many people don't know about.
To open the brightness panel:
- Swipe down from the top edge of the screen to open the notification curtain.
- Find a slider with a sun icon (usually at the top).
- Move it to the right to increase the brightness.
If the slider isn't there, it might be hidden.
- Open the Settings. β Notification curtain and control panel.
- Select the Control Panel setting.
- Find the Brightness element and drag it to the active area.
Settings menu β The display also has a separate section for adjusting the brightness:
- π Enable/disable automatic adjustment (more on this in the next section).
- π Activate reading mode (reduces blue light but does not affect brightness).
- π± On some models (Redmi Note 11 Pro, K50) Here is the option "Contrast", which indirectly affects the perception of brightness.
π‘
After the update MIUI The brightness slider is gone from the curtain, so try rebooting your phone.
Please note: Redmi with AMOLED-screens (for example, Note 10 Pro, K40) Maximum brightness in manual mode is often limited ~80% of the actual display potential. This is done to save power, but you can bypass the limitation (read the section on hidden settings).
2. Automatic brightness control: pros and cons
Adaptive brightness function in MIUI It's supposed to make life easier in theory, because the phone adjusts the lights to the lights, but in practice, many Redmi users complain that the automation is not working properly, because the screen is too dim during the day or blinds at night.
How to adjust adaptive brightness correctly:
- Go to Settings. β Display. β Automatic brightness control.
- Activate the switch.
- Click on Adaptive Brightness Settings (if the option is available).
- Calibrate the light sensor by following the instructions on the screen (usually point the phone at the light source and confirm the current lighting).
If after calibration the brightness still does not suit:
- π§ Try resetting the sensor settings: turn off adaptive brightness, restart the phone, then turn it on again.
- π On some firmware (MIUI 14+) There's a hidden "Smart Brightness" mode that takes into account your preferences, and to activate it, you need to manually set the desired brightness level under different lighting conditions (the system will remember your actions).
- π« If the automation is not working well, it is better to turn it off and control the brightness manually.
An important feature for owners of Redmi with AMOLED-displays: adaptive brightness can reduce the maximum level of backlighting 15-20% Even in bright sunshine, to save charge. If you want maximum brightness, turn off automatic adjustment.
3. Hidden brightness settings in MIUI
The manufacturer does not always disclose all the capabilities of their smartphones. MIUI There are several hidden features that allow you to increase the brightness above the standard limits.
Method 1: Ultra-brightness mode (for AMOLED-model)
On the phones with AMOLED-screens (Redmi) K50, Note 12 Pro+, K60) There's a hidden mode that activates in bright sunlight to force it to turn on:
- Open Settings β Special Opportunities β Improve visibility.
- Activate the option to increase contrast (on some firmware it is called High visibility).
- Back to Settings β Display and set the brightness to maximum.
This mode increases the brightness of the 20-30% Changes in color profile, but may slightly distort colors.
Method 2: Engineering menu (only for power users!)
You can manually increase the brightness limits through the engineering menu, but it is risky:
- Open the Phone app and type ##36446337##.
- Go to the Display or Screen section.
- Find the Max brightness or Backlight level settings.
- Increase the values by 10-15% from the present (do not exceed the 255 backlight!).
What happens if you set the maximum values in the engineering menu?
Method 3: ADB-brightness-blocking
If the engineering menu is not available, you can use ADB:
- Connect your phone to your PC and activate Debugging USB at the Settings β The phone. β Version. MIUI (Click 7 times on the line with the version).
- Enter the command line: adb shell settings put system screen_brightness_mode 0 adb shell settings put system screen_brightness 255
This will reset the brightness limits, but after the phone reboots, the settings may reset.

Hidden brightness modes can greatly improve screen visibility in the sun, but abuse of them shortens the life of the display.
4. Color profile setting for better visibility
Sometimes the problem isn't brightness, but color temperature or contrast, and you can adjust these settings on Redmi to improve your screen experience.
How to change the color profile:
- Go to Settings β Display β Color mode.
- Choose one of the options: π Saturated β increases contrast but can distort colors. βοΈ Standard β Balance between Realism and Visibility. πΊ sRGB (on some models) is the most natural color reproduction, but may appear duller.
For models with AMOLED (Redmi K40, Note 11T Pro) additional settings available:
- π¨ Settings β Display. β Color mode β Manual adjustment β here you can increase the saturation of red / green / blue to improve contrast.
- π Contrast option (if any) β move the slider to the right for a clearer image.
On Redmi with IPS-screens (Note 10, 9A) These settings are less effective, but they can still improve visibility a little bit.

5.The effect of brightness on the battery: how to save charge
Many people are afraid to increase the brightness, fearing that the battery will die in a couple of hours. Indeed, the screen is one of the main consumers of energy, but there are ways to minimize the impact.
Tips for saving charge at high brightness:
- β‘ Use dark themes and wallpaper: AMOLED-Black pixels are not illuminated, which saves up to 15% of charge.
- β±οΈ Set up automatic screen shutdown through 15-30 seconds of inactivity (Settings) β Display. β Sleeping mode).
- π Enable the Power Saving Mode (Settings) β Battery, but note that it can limit performance.
- πΆ Turn off auto-update applications in the background (Settings) β Annexes β Auto-start).
Comparison of power consumption at different brightness (test on Redmi Note 11 Pro)+ 5G):
| Brightness (%) | Hours of operation (video) | Working hours (web surfing) | Discharge in 1 hour (%) |
|---|---|---|---|
| 30% | 12:45 min. | 10:30 min. | 6-8% |
| 50% | 9:20 min. | 7:50 min | 9-11% |
| 70% | 7:10 min | 6 hours 05 minutes | 12-14% |
| 100% | 5:30 min. | 4:40 min. | 16-18% |
| 100% + Ultra Brightness | 4:50 min | 4:10 min. | 20-22% |
As you can see from the table, the transition from 70% to 100% brightness increases the discharge by ~30%, but if you really want maximum visibility, this trade-off is justified.
π‘
On models with a battery of 5000+ mAh (Redmi Note 12 Pro)+, K60 Ultra) even at 100% brightness, the phone will last all day with moderate use. Don't skimp on brightness at the expense of comfort if the battery capacity allows it.
6.Brightness problems: diagnosis and solutions
If the screen stays dim even at maximum settings, there may be hardware or software malfunctions, and let's look at typical problems and their solutions.
Problem 1: The screen is dimming on its own
Possible causes and solutions:
- π Battery worn out - with a low charge (<15%) system automatically reduces the brightness. Check the battery status in Settings β Battery β Status.
- π± Overheating - at temperatures above 40Β°C is limited. Let the phone cool down.
- π οΈ Firmware failure - try resetting the display settings: Settings β System system β Resetting settings β Reset the display settings.
Problem 2: The brightness adjustment is not working
What to do:
- Reboot the phone.
- Check if the charge saving or ultramode mode is activated β they can block the change in brightness.
- Update the firmware: Settings β About the phone β System update.
- If nothing helps, reset your phone to factory settings (donβt forget to make a backup!).
Problem 3: Uneven brightness (spots, dimming)
It could be a matrix defect or a backlight defect.
- π¦ Turn on a white background (open an empty document or photo) and see if there are dark spots.
- π If the defect is confirmed, contact the service center (on phones up to 2 years old this is a warranty case).
What if the screen becomes dim after falling?
β οΈ Attention, if after the update MIUI The screen is dim, and the settings are not helping -- check the firmware version. MIUI 14 for some models (Redmi 9, Note 8 Pro) was a brightness-limiting bug.Solution: roll back to the previous version or wait for a patch.
7. Alternative ways to improve screen visibility
If you can not increase the brightness, you can go another way - to improve the contrast and readability of the screen.
Method 1: Use dark themes and wallpapers
Nana AMOLED-The black color does not require lighting, so:
- π Set a dark theme: Settings β Display. β Dark subject.
- πΌοΈ Choose black wallpaper (you can download special ones). AMOLED-Google Play wallpaper).
- π± Enable Reading Mode (Settings) β Display. β Reading Mode β It reduces blue light and improves text contrast.
Method 2: Increase the font and scale
Sometimes the problem is not the brightness, but the text is too small.
- Go to Settings. β Display. β Text size and increase the font.
- Activate the Display Scale (if available) to zoom in on all interface elements.
Method 3: Applications for improving visibility
Google Play has some tools that artificially increase contrast:
- π Lux Auto Brightness β allows you to more accurately adjust adaptive brightness.
- π Screen Filter β adds a layer of dimming or lightening over the interface.
- π Night Shift β Reduces blue light, which indirectly improves text perception.
β οΈ Attention: Forced brightnes applications can cause the screen to overheat. IPS-Redmi models. AMOLED The risk is less, but it is still not recommended to use such utilities constantly.
